Redis

Towbar’s redis preset runs Redis 8 Alpine on amd64 or arm64. It listens on port 6379, stores data in /data, enables append-only persistence, and requires password authentication for health and managed operations.

Declare the resource

.towbar/resources/redis.resource.yml

id: redis
name: Redis
type: redis
container:
  network: application
  networkAlias: redis
  resources:
    cpus: 0.5
    memory: 512m
access:
  sshTunnel:
    hostPort: 16379
secrets:
  runtime:
    - REDIS_PASSWORD
environments:
  production:
    server: 192.0.2.10

REDIS_PASSWORD is required. Towbar injects it into the managed Redis command and uses the same value for authenticated health checks, backups, and restores.

Connect from an app

Containers on the application network can reach redis:6379. Save a URL such as redis://:PASSWORD@redis:6379/0 in the app’s runtime secrets. The optional SSH tunnel binds 16379 only to server loopback.

Change the password

Replacing REDIS_PASSWORD changes the command used by the next deployment, but it is still an operational credential change. Coordinate clients before redeploying, verify that they use the new value, and keep a tested rollback path.

Back up and restore

Towbar requests and verifies an RDB snapshot. Restore starts a fresh isolated target, verifies the dataset, re-enables append-only persistence, and promotes the target only after it is ready. Recovery requires Redis major version 8. Continue with Database backups and Database restores.
